lgACHINE FOR THE MECHANICAL APPLICATION 01' PAINTS AND OTHER HQ'UIEPE i To all whom. it may concern:

Be it known that I, Josurn Em MAYO, a citizen of the United States, residing at Sacramento, in the county of Sacramento plied and distributed .by necl mical means.

he object of the invention is the applying of paint mechanically by jneans of a revolving brush. The paint is applied to the eri hery of a revolving brush when the rus has been compressed. The object is y to provide in a machine of this kind a novel :construction and arrangement of arts to be hereinafter described and claime whereby a strong, durable and eflicient machine is produced. a

In order that the invention may be better understood, reference is made to the accompanying drawings, which form a part of this specification, in which:

Figure 1 is a perspective view of the complete machine; Fig. 2 is a top assembly plan view with the paint box (1) removed; Fig. 3 is a front assembly and new with the paint box (1) removed; Fig. 4 is a detail of the brush spindle and sprocket; Fig. 5 is' an end view of brush spindle and sprocket; 6 is the brush clutch yoke; Fig. 7 is a. si e view of the circular brush; Fig. 8 is an end view of circular brush; Fig. 9 is a side view of feed box chamber and oompressin die; Fig. 10 is an end view of feed box an com ressing die; Fig; 11 is a section through fee box chamber; ig. 12 is a side view of adjustable guides; and Fig. 13 is an end view of adjustable guides.

Referring s ecifically to the drawings, the paint tank .(1 is supported on the framing (2) which also serves to brace the machine and the handles (3 The aint or fluid contained in tank 1) is f through the feeding tube (4), vhem admitted to feed box chamber (6) See lgs. 1, 9, 10 and 11 through the hollow stem feed valve (5) which allows afree and unobstnmted flow.-

7", the valve being norlhally held in closed position by action of spring (9). The paint being admitted through. opening (27) to feed chamber (6) flows through 0 emn (10) and is uniformly distributed t roug the brush (11). i

The brush (11) is driven by sprocket (l2) and chain (13), which receives power and motion from sprocket (38) attached to wheel (14). J The lever handle (16) actuates the hinged toggle (17) connected to clutch yoke (18) and opprating clutch dogs (19) which pass throng holes in the hub (292 of brush (11) and which engage with lugs 31) which are secured to axle (20) the clutch do (19) being normally kept from c aging t e lugs ('31) by action of spring (21 Spacing plate (22) regulates and restricts the width of surface covered by brush (11), and is attached to brush guide frame 23). The frontand rear separator rods 43) and guide frame (23), whose ugs (24) and,(45

i 7 5 (44) act as spacer and su port for t e brush ,support short rods (25) the lower ends of which pass loosely through lugs (45) and support lower, movable part of brush ide frame (23). Attached in front of the ower part of the brush idc frame (23) is a shoe (26). l h

26 ands acin pate 22 a instt esur face? over hich the machine -ziay be moving and take up unevennesses of surface.

The springs (46) hold the shoe The frpnt roller (41) supports the front end of the machine and regulates a maximum compression of the bristles of brush (1 1) is surface to. be painted, the bracket (42) be adjustable and secured to main frame 10) which supports the movable parts;

The feed box adjusting screws (33) are attached to feed'box (15) and pass through holes in frame when eed box (15)is fitted in place overbrush 11). Top ad uSter rod (343 attached hinged to extended sides of ee box (15) permits further adjustment of feed box (15). The cover 32) of feed box chamber (6) is packed wit a composition washer to prevent leakage of paint, and is separate from feed box (15) to facilitate cleaning. The spindles (28) are threaded part of their length to corresponding threads within axle (20) for the purpose 0 permitting brush (11) to be removed for cleaning, the spindles being unscrewed allow brush (11) and axle (20) to drop out of frame (40).

It will be noted that as the ends of the bristles of brush (11) come in contact with face and sides of feed box (15) as shown by the'clotted lines, F ig. 11, the brush is gradually eoinprcsseddue to the die being narrower than brush, and the compressing face ofthe feed box, Fig. 10, decreasing in distance to the center of the hub of the brush, so that the bristles of the brush are bent backward and the maximum compression occurs at the opening (10) through which the brush receives its charge of paint from the feed chamber ((3). The brush is gradually expanded to its normal shape and size before leaving the feed box, the entire operation of the combination of the brush (11) and the feed box being similar to the taking up of paint with a brush by hand and distributing it properly within the brush )reparatory to painting.

The rush is geared in such a manner as to revolve at increased speed so that bristles flow evenly over surface to be painted with a strong brushing action. The brush (ll) can be disengaged from shaft (20) by releasing the clutch, so that the operation of the brush is under the direct control of the operator, as well as the supply of paint to the feed chamber.

The structure herein described is a handiower machine with a relatively narrow rush, but the invention includes the use of other motive power and large brushes, singly or inmmhiuation, with corresponding modifications of the details of the machine. Various other changes and modifications of the structural details may be made without a departure from the scope and spirit of the invention, as well as other fluids than paint may be used with benefit.
